Apple today temporarily lowered the prices of some of its accessories for connecting to its new MacBook Pro laptops, each of which comes with up to four USB-C ports and a headphone jack but no other ports.

The price of the Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter is also being dropped from $49 to $29. That’s interesting, as some reports have indicated that the MacBook Pro might not be compatible with all Thunderbolt 3 accessories.

Additionally, Apple has lowered the prices of the LG displays it announced at the MacBook Pro event last month, MacRumors reports. The LG UltraFine 5K Display now costs $974, down from $1,300, and the LG UltraFine 4K Display costs $524, down from $700. As is the case with the adapters, these discounts are available through December 31.
